Shia LaBeouf got into the swing of things at the T-Mobile Sidekick LX launch party on Tuesday.

After downing a Malibu rum cocktail, the 21-year-old “It” boy, whose skills on the golf course were honed in The Greatest Game Ever Played, eschewed the party festivities when he saw a vacant driving range at the adjacent Griffith Park Golf Course Club House, according to an eyewitness.

The Indiana Jones star sure takes his game seriously too.

“He seemed to be enjoying the female attention,” the source tells OK!. “But golf won out and he practiced his strokes with his boys instead.”
